HYDRANT.

SPECIFICATION forming part of Letters Patent No. 451,772, dated May 5, 1891.

Application filed February 10, 1890. Serial No. 339,852. (No model.)

To @ZZ whom, t may concern,.-

Be it known that I, JOSEPH REDICAN, a subject of the Queen of Great Britain, residing in the city of Toronto, county of York, Province of Ontario, Canada, have invented new and useful Improvements in Hydrants, of which the following is a specification.

My invention relates to improvements in hydrants, in which the cut-off valve at the main is connected to and operated by a rod which passes through the center and projects through the top of the hydrant to receive the crank-handle, and the object of the invention is to construct a cut-off valve Within the hydrant-plugs, which will, if required, shut off the water automatically without the necessity of turning off the Valve at the lnain and it consists, essentially, of a valve located at the inner end of the hydrant-plug and connected to a cylindrical sleeve which movesv within the plug, the said sleeve having two pins secured to it which move longitudinally in slots cut in the plug, and carry the valve from its seat when the coupling of the hose is being screwed in, but when the valve is unscrewed the pressure of the water causes the valve to resume its initial position and shut off the water, substantially as hereinafter more particularly explained.

Figure l is a perspective outside View of a hydrant. Fig. 2 is a perspective sectional detail exhibiting my invention. Fig. 3 is an alternative form of valve.

In the drawings like letters indicate corresponding parts in each figure.

yA represents the hydrant-plug, leaded or otherwise, suitably secured to the body of the hydrant.

B is the cut-off. valve which is connected by the rod O to the cross-bar D, which is formed in the cylindrical sleeve E, the rod C being secured to the cross-bar D by the nut F.

G are pins screwed into the cylindrical sleeve E and secured by the nut F, or fastened to the sleeve E in any other suitable manner.

I is a slot through which the pins G project, and J is the hose-coupling.

In Fig. 3 it will be noticed that the valve and cylindrical sleeve E are connected together by three cross-pieces C, so as to leave open spaces for the escape of the water.

Having now described the parts involved in my invention I shall brieiiy describe their operation.

The hose-couplings are screwed ou to both hydrant-plugs in the ordinary way before the Water is turned on at the main by the central valve-rod. In so screwing them on, the coupling J presses against the pins G and forces back the cylindrical sleeve E in the plug A, thus pushing the valve B from its seat sufciently far to admit of the free escape of the Water. The Water is now turned on at the main and makes its way freely through the plugs into the hose. Should, however,one of the hose burst, as is often the case at a fire, instead of turning oif the water at the main and thus preventing the use of the other length, it is merely necessary to unscrew the one length, when the pressure of the water will immediately close the valve and prevent the escape of the water. Another length of hose may now be immediately substituted, and as it is being screwed on will reopen the valve and again permit the free escape of the water through the hose.

It will be seen that either coupling may be taken off at the will of the fireman or person using the hose, and taken to another hydrant without in any way interfering with the flow of the water. It will also be understood that the water may be turned on full, and the valves being self-closing prevent the escape of the water until the coupling or couplings of the hose are attached.

VVh'at I claim as my invention is- 1. In combination with a hydrant and its plug-A, a Valve seated at the inner end of said plug, a sliding sleeve within the plug connected to the valve, the said plug having a longitudinal slot and being threaded outside to receive the hose-coupling, and the pin G, attached to the sleeve and projecting therefrom through the slot and into proper position to be moved by the coupling when the same is screwed thereon, the said sleeve being arranged to cover the slot in the plug, substantially as described.

2. In combination, the hydrant with its slotted plug A, the valve B, the sliding sleeve E, said valve and screw being connected rigidly, and the pin G, projecting through the slot of the plug and adapted to be borne against by the hose-coupling, substantially as described.

JOSEPH REDICAN.
